Abstract

The utility model relates to an incised type hydraulic tube slab shear, which is characterized by comprising a rack, an upper scissors support seat, upper scissors, a steel slab balance tile, lower scissors, a ram, a super high pressure hydraulic plunger cylinder and a boost cylinder, and uses an incised hydraulic multi-cylinder drive structure mode, wherein the rack is provided with the upper scissors and the lower scissors, the upper scissors are arranged on the upper scissor support seat, the lower scissors are arranged on the ram, the steel slab balance tile is arranged on the lower scissors, and the super high pressure hydraulic plunger cylinder which is arranged on the rack is connected with the boost cylinder. The incised type hydraulic tube slab shear has the advantages of small investment, energy conservation, low noise, no oil pollution, less maintenance, low maintenance cost and safe and reliable performance. Compared with cutting equipment, the incised type hydraulic tube slab shear has the advantages that the incised type hydraulic tube slab shear reduces consumption of tools, does not have incision, saves power, saves maintenance cost, improves work rate and the like, and has obvious economic benefits.

Description

Lower cut penstock base cutter

Technical field

The utility model belongs to metallurgy industry metal pipe billet cutting technique field, particularly a kind of lower cut penstock base cutter.

Background technology

At present, domestic metallurgy industry adopts the cutting of the various metal materials such as pipe in the prior art: 1, flywheel energy release type cutting machine, this technology take shape in and are widely used till now the fifties in last century.But exist significantly not enough: a. equipment is too large, complicated; B. equipment fault is easily sent out a little too much, causes that maintenance cost is high, equipment is made rate too low; C. electric energy loss is more than 60%; D. the metal surface stress that produces because of otch makes greater than the yield strength of cutting metal material the Plastic Deformation of Metal Materials of cutting, so the product quality that this kind equipment is produced is bad, for hot rolled seamless steel tube, directly affects tube quality; E. noise is too large, and greasy dirt is large, and working environment is too dangerous.2, fire combustion cutting machine or artificial fire combustion cutting, its principle is simple, but exists: pernicious gas is too many, and human body is had injury; (15～25mm), metal loss is many due to obvious otch being arranged; Otch is out-of-flatness extremely; The acetylene consumption is too large, wastes energy.3, adopt sawing: exist: the wide 15-20mm of circular saw otch, make recovery rate of iron lose 1% left and right in hot rolled seamless steel tube is produced, ton steel cost rises 55～75 yuan; Ton disc saw or saw blade consumption are 20 yuan of left and right; The problems such as noise is large, efficient is low, power consumption is large.4, breaker: exist backward in technique, investment is large, poor product quality, genus obsolete product.

Summary of the invention

The utility model has overcome the defective of above-mentioned existence, purpose be for solve large specification Metal Cutting equipment huge, complicated, of poor quality, consume the difficult problems such as large, that cost is high, poor working environment, efficient are low, a kind of lower cut penstock base cutter is provided.

Cut penstock base cutter content Description under the utility model:

Cut penstock base cutter under the utility model, it is characterized in that: formed by frame, upper scissors bearing, upper scissors, steel billet balance watt, lower scissors, ram, ultra high water pressure plunger case and pressurized cylinder, the frame mode that adopts lower cut, hydraulic pressure multi-cylinder to drive, be provided with the upper scissors that is arranged on the scissors bearing and the lower scissors that is arranged on ram in frame, be provided with steel billet balance watt on lower scissors, the ultra high water pressure plunger case that is arranged on frame is connected with pressurized cylinder.

Cut penstock base cutter under the utility model, have the investment little, energy-conservation, noise is low, without greasy dirt, maintenance capacity is few, maintenance cost is low, the reliable characteristics of performance safety, can greatly improve working environment, compare with sawing device, the characteristics such as instrument consumption reduction, non-incision, economize on electricity, saving maintenance cost, raising operating rate have significant economic benefit.

Description of drawings

Fig. 1 is lower cut penstock base cutter structural representation;

In figure: the 1st, frame, the 2nd, upper scissors bearing, the 3rd, upper scissors, the 4th, steel billet balance watt, the 5th, lower scissors, the 6th, ram, the 7th, ultra high water pressure plunger case, the 8th, pressurized cylinder.

The specific embodiment

under the utility model, cut penstock base cutter is to realize like this, illustrate below in conjunction with accompanying drawing, see Fig. 1, lower cut penstock base cutter, by frame 1, upper scissors bearing 2, upper scissors 3, steel billet balance watts 4, lower scissors 5, ram 6, ultra high water pressure plunger case 7 and pressurized cylinder 8 form, adopt lower cut, the frame mode that the hydraulic pressure multi-cylinder drives, be provided with the upper scissors 3 that is arranged on scissors bearing 2 and the lower scissors 5 that is arranged on ram 6 in frame 1, be provided with steel billet balance watts 4 on lower scissors 5, be used for reducing metal surface stress, lower scissors 5 is arranged on ram 6, by the fixing lower scissors 5 of ram 6, the balance shearing force, ram 6 also plays guiding.The ultra high water pressure plunger case 7 that is arranged on frame 1 is connected with pressurized cylinder 8, produces high-pressure water and promotes shearing force.

Cut penstock base cutter under the utility model cuts off apparatus field at seamless steel tube blank and utilizes the incision mode, and the ultra high water pressure that adopts pressurized cylinder to produce by oil pressure drives super-pressure plunger case or piston cylinder as shearing power source.Super-pressure plunger case or piston cylinder adopt and disperse to distribute to increase the frame non-deformability.Increase cutting edge thickness or add on the cutting edge supporting seat with the supporting rod iron of cutting edge and support watt, be out of shape with solving the termination.Have investment little, be equivalent to 20% of equal shearing force tradition mechanical shear off line; Energy-conservation: power consumption cuts off equipment 18% for other form of ownerships; Reducing noise, without greasy dirt, safety, reliable, greatly improve working environment; The maintenance of equipment amount is few, and maintenance cost reduces more than 95% than other form cut-out equipment; Compare with sawing device, instrument consumption reduces by 99.3%, produces the seamless steel tube production chain of 100,000 tons per year and can save 2,000,000 yuan; Instrument consumes: the composite factors such as non-incision, economize on electricity, saving maintenance cost, raising operating rate make ton steel cost reduce by 115 yuan of left and right, and significant economic benefit is arranged.
